Complete the square to make a perfect square trinomial. Write the result as a binomial square. q2−23q
tia_tia [17]

Answer:

\left(q-\dfrac{23}{2}\right)^2

Step-by-step explanation:

Given the expression: q^2-23q

To complete the square, we follow these steps:

Step 1: Identify the coefficient of q

Coefficient of q=-23

Step 2: Divide the coefficient of q by 2

=-\dfrac{23}{2}

Step 3: Square your result from step 2 and add it to the equation

This gives us: q^2-23q+\left(-\dfrac{23}{2}\right)^2

We have now completed the square.

Step 4: Write the result as a binomial square.

To write it as a binomial square, pick the variable and add the term in the bracket.

Therefore:

q^2-23q+\left(-\dfrac{23}{2}\right)^2=\left(q-\dfrac{23}{2}\right)^2
